Specification of Letters Patent.

Patented Nov. 25, 1913.

To all whom it may concern:

Be it known that we, ROBERT T. SIMMoNs and WILLIAM R. SIMMONS, citizensof the United States, residing at Wynne, in, the county of Cross, Stateof Arkansas, have invented a new and useful Cotton-Cultivating Machine,of which the following is a specification.

This invention relates to an attachment for use primarily in thecultivation of cotton, one of the objects of the invention being toprovide an attachment of this character which can be applied readily todifferent types of wheel cultivators, the said attachment includingnovel means for weeding the soil and for chopping cotton plants.

Another object is to provide simple means under the control of theoperator whereby the operation of the chopping and weeding mechanism canbe controlled. 1

With the foregoing and other objects i view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings :Figure 1 is a side elevation of a cultivator havingthe present improvements combined therewith, the axle of the cultivatorbeing shown in section. Fig. 2 is a section on line A-B Fig. 1. Fig. 3is a rear elevation of the cotton chopping device. Fig. 4 is a detailview of one of the chopping blades. Fig. 5 is a side elevation of amodified structure for use in weeding.

Referring to the figures by characters of reference 1 designates thearched axle, 2 the supporting wheels and 3 the beam of an ordinarycultivator.

Mounted on the arched axle 1 is a standard 4 the base of which is shapedto fit snugly on the axle and has laterally extending ears 5. A clampingplate 6 extends under the axle and under the ears 5 and is connected tosaid ears by means of bolts or the like. A lever 8 is fulcrumed, as at 9upon the standard 1 and extending rearwardly from the standard is a nose10 adapted to be engaged by a projection 11 extending laterally from thelever 8. A hooked tongue 12 extends from the front end of lever 8 and isfor the purpose hereinafter set forth.

Clamped or otherwise secured to the beam 3 is a hanger 13 provided witha brace 14 likewise clamped or otherwise secured to the beam. Pivotallyconnected to the lower end portion of the hanger 13 is a tongue 15having a plurality of apertures 16, any one of the side frame members 19being extended downwardly to form hangers 22 located back of and spacedfrom the main frame 21 of the attachment. An axle 23 is mounted forrotation in the main frame 21 and is supported by wheels 24 adapted totravel over the ground. These wheels constitute means for rotating theaxle and a gear 25 is secured to and rotates with the axle and mesheswith a smaller gear 26 located at the front end of a longitudinal shaft27 journaled in the frame 21. Secured to that end of the shaft 27 backof the frame 21 is a sprocket 28 on which is mounted an endless chain29, this chain extending around a smaller sprocket 30 which is supportedby a laterally extending bracket 31 mounted on one side of the mainframe 21 of the attachment.

Lifting chains 32 extend downwardly from the hooked tongue 12 to thefront end portions of the side frame members 19 and additional chains 33may be extended from the rear portions of said side frame membore 19 andforwardly and upwardly to the chains 32.

The downwardly extending rear end portions 22 of the side frame members19 extend back of an angle strip 3 1 and placed back of this angle stripand between the downwardly extending portions 22 is a filling block 35preferably of wood. A- clamping plate 36 extends along the back face ofthe filling block and across the back edges of the portions 22 and isconnected to the angle strip 34 by bolts 36. t

Bearing downwardly on the 'angle strip. 34 and beyond the sides of theframe mem- I bers 19 are spring teeth 37 fastened to the angle strip inany suitable manner, as by means of bolts 38.. A clamping strip 39eX-Qadapted to receive the feet of the person oc-f jcupying the seat 42mounted on beam 3. W ithth i's arr a'ngeme'nt of parts it will be seenthat the teeth '37 can be adjusted upwardly and downwardly along theportions '22 of the 'sideframemembers 19, this adjustmen't beingeffected by loosening bolts 36 so as to permit the strip 34, to be slidalong the portions 22 of the side frame members and the filling block35. This block is fixedly mounted. Certain of the teeth '37 have tongues'42 extending forwardly therefrom and adapted to be engaged by rods 43such as found inmost Cultivators and which are utilized in regulatingthe depth of the furrows. As this rod 43 and its chain connection 44does not constitute a part of the present invention, it is not deemednecessary to specifically show and describe it.

When the machine herein described is to be used for chopping cotton,certain of the links of the chain 29 are provided with outstandingtransverse lugs 45 to which are secured the inner or butt ends ofchopping blades 46. As shown in Fig. 4, each chopping blade has its sideedges preferably diverging outwardly, theouter end portion of each bladebeing curved, as shown particularly in Fig. 3. These blades can beplaced at any desired intervals apart and it will be apparent that, asthe machine is moved forward, the wheels 24, by reason of theircontacting with the ground, will rotate and cause the gear 25 to revolvewith them. Thus motion will be transmitted through gear 26 and shaft 27to sprocket 28 and the chain 29 will be actuated in the directionindicated by the arrow in Fig. As the attachment is designed to straddlethe row of cotton or other plants being actedon, the blades 46 will bemoved transversely of the row and'will cut therefrom any plants in thepaths thereof. By utilizing chains which are provided with blades 46 atcertain intervals it will be seen that, durin the operation of themachine, certain of the plants will be skipped and thus left standing.Should it be desired'to use the machine for weeding, blades such asshown at 47 in Fig.

5 are substituted for the blades 46, these teeth or blades 47 beingpreferably pointed as shown and being attached to one side of the chain,Each link of the chain is provided with one of the teeth or blades sothat, as the machine moves along, the blades will cut transversely amongthe weeds and "cause them to be ra'ked out of the soil immediatelysubsequent to the cutting operation. In other words, those of the teeth47 extending downwardly f'coeperate to form both a rake and a laterallymovable cutting means.

It is to be understood of course that if'desired the teeth 37 can beused either independent'ly of'or in connection with the trans verselymovable soil engaging devices for cultivating the soil.

By shifting lever 8 laterally so as to removep'rojec'tion 11 from underthe nose 10, the tongue 12 is left free to swing downwardly, thus topermitthe attachment to move downwardly relative to the cultivator. Bypulling downwardly onto the handle end of lever 8 and shifting saidlever laterally to bring the projection 11 into engagement with noselO,the parts are held raised or in inactive positions. Qbviously the chains32 and33 can be adjusted relative to each other and to the tongue 12simply by hooking different links into the tongue 12 and by placingdifferent links of "the two chains into engagement with each other.

What is claimed is:

The combination with a cultivator including a wheel supported axle, ofan attachm'ent under the axle and including a wheel supported frame.side frame members connected thereto and having downwardly extendingrear portions, an angle strip adjustable vertically along said portions,means for clamping the strip upon said portions to hold it againstmovement, soil engaging teeth secured to and extending rearwardly fromsaid strip, a chopping means supported by the frame and in front of saidstrip,

and means operated by one of the supporting wheels for actuating thechopping means during the forward movement of the Wheel. In testimonythat we claim the foregoing as our own, we have hereto affixed oursignatures in the presence of two witnesses.
